SPECIFICATION forming part of Letters Patent No. 349,127, datedSeptember 14, 1886.

Application filed March 9, 1886.

- Be it known that we, FRANKLIN THOMAS and GEORGE M. KAY, of 'Letart, inthe county of Mason and State of West Virginia, have invented a new andImproved Single-Tree, of which the following is a full, clear, and exactdescription.

This invention relates to a single-tree whereed to be easily. withdrawnfrom the traces for detaching the horse in case he becomes unmanageable;and the invention consists in the construction, arrangement, andcombination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding-parts in both thefigures.

Figure l is a broken rear elevation of our new and improved single-tree,showing the traces held by the spring-hooks; and Fig. 2 is aplan view ofthe same.

The wooden portion Aof the single-tree has the central passage, a, madethrough it, by which it may be attached to thills or to a double-treefor use. At its ends the singletree is strengthened by the iron or steelplates b, which clasp and protect the single-tree at its upper and loweredges, the plates being secured by the through-bolts or rivets c c.

d d are horizontal passages made in the singletree nearits ends, inwhich the traces B B are held by the points e e ofthe spring-hooks G O,which points reach down through the vertical openings ff, made throughthe single-tree and plates 2) in line with the center of the horizontalpassages d.

The hooks O are looped to form the eyes 9 Serial No. 194,571. (Nomodel.)

In the eyes 9 are placed thelinks j, to which 7 the ends of thedetaching cord or rod D are attached,and secured to the single-tree soas to straddle the plates h are the U-shaped irons E E,which serve,first, as guides to the up and down movement of the hooks G, and,secondly, as stops to the upward movement of the hooks O, to preventthem from being raised upward too far by pulling upon the cord D or thecord D, which is attached to the center of the cord D, and is designedto reach to or into the vehicle in easy reach of the driver, so that incase of any accident, or in case the horse or horses becomeunmanageable, by pulling upon the cord D, the hooks C may be lifted soas to raise the points eout of the traces B, and thus detach the horseor horses from the vehicle.

Having thus described our invention, what we claim as new,and desire tosecure by Letters Patent, is

The combination, with the single-tree A, having the trace-apertures (lin its ends, of the springs O, looped to form the eyes g, and then bentdown to form the points 0, the keepers E, the links 7', secured in theeyes 9, and the cords or rods D, secured to the links, substantially asherein shown and described.
